Alright, a business man was driving late at night, when his car broke down, so he signaled a pickup truck to pull over. A farmer came out and said, "What seems to be the problem?" so the business man told him all about it. Then the farmer said that since he didn't have his tools, they would go back to his farm in the pickup truck, get tools and come back.
But, by the time they got back to the house, it was around 3 in the morning, so the farmer said, "How about we get some rest, and go fix your car in the morning." To which the business man happily agreed. The farmer led him to an empty stable and said, "You can sleep here for the night, but whatever you do, do not stick your cock in the cornhole." So the business man thought this was a fair enough agreement and the farmer went on his way.
So, the business man was lying awake, wondering what was so bad about the cornhole, he eventually decided that he would stick his cock in the cornhole, to see what was so bad.
The farmer woke up in the morning, and headed toward the stable. When he got there he found the business man lying on th ground, holding his crotch in pain, naked. "You stuck your cock in the cornhole, didn't you?" said the farmer. The business man replied, "Ya, what's in that thing?" To which the farmer replied:
"It's the milksucker, doesn't stop 'till it gets a gallon!"
